T0 all whom t may concern.'

Be it known that I, FREDERICK W. PEN- Dnnoasr, a citizen of the United States, and a resident of Cambridge, in the county of Middlesex and State of Massachusetts, haveV invented certain new and useful Improvements in Mops, of which the following 1s a specification.

This invention relates to mops composed of fibrous strands of cotton yarn or thread adapted to be detachably secured to a handie.

The invention has for its object to provide a mop of this character of simple and relatively inexpensive construction adapted to be manufactured without the employment of special appliances.

The invention consists in the improvements which I will now proceed to describe and claim. n

Of the accompanying drawings: Figure 1 represents a side view illustrating the rirst stage of operation of making my improved mop. Fig. 2 represents a section on line 2-2 of Fig. 1. Fig. 3 represents a View similar to Fig. 1 showing the second stage of the operation. Fig. 4 represents a side view of the complete mop and a portion of the handle adjacent thereto. Fig. 5 represents a view of the inner end of the mop as shown by Fig. 4. Fig. 6 represents a section on line 66 of Fig. 5. Fig. 7 represents a perspective view of the part hereinafter called the hub.

The same reference characters indicate the same parts in all the figures.

In the drawings 12 represents a hub which is preferably made of a malleable metal such as malleable iron or brass, and is adapted to detachably engage a handle 18. the hub being preferably provided with a screw threaded socket 14 adapted to engage a screw threaded shank 15 on the handle. The end portions of the hub are enlarged by means of a flange 16 on the outer end of the hub and ears 17 on the inner end of the hub, said ears being preferably forked as sho-wn by Fig. 7. The ears project in opposite directions from the hub and the outer ends of their prongs are inclined inwardly toward each other to confine between the prongs groups of fibrous strands inserted in the recesses between the prongs. Around the hub 12 I group a multiplicity of elongated fibrous strands 18 as shown by Fig. 2, the strands being laid side by side with their central portions covering the hub and their end portions projecting at substantially equal distances from the hub. 'Groups of the strands are pressed into the recesses between the prongs of the ears 17 and are closely confined in said recesses,the malleability of the prongs enabling their points to be bent inwardly toward each other to more closely confine said groups. I next bind the central portions of the strands upon the hub by means of a ligature 19 preferably of wire, which compresses the central portions of the strands between the enlarge? ments 16 and 17 as shown by Fig. 3. By thus confining the strands I convert them into two series of mop filaments which at this stage of the operation project in opposite directions from the ends of the hub. I then bend backwardly the filaments of one series, namely, that projecting from the outer end of the hub, over the ligature 19 as shown by Figs. 4 and 6, thereby exposing the outer end of the hub, the backwardly bent series of filaments covering the other series and the outer ends of the ears 17 so that the two series are assembled and collectively form a thick mass of filaments extending from the inner end of the hub. The groups of filaments confined between the prongs of the ears 17 support the backwardly bent filament portions, so that the latter cannot be pressed inwardly far enough to permit the outer ends of the prongs to project from the exterior of the mop and injure mop boards or other surfaces with which the mop comes in contact. Some of the filaments of both series are engaged with the ears 17, numerous filaments entering the spaces between the prongs o-f said ears and others bearing on the outer edges of the ears. The mass of filaments is therefore prevented from turning on the hub.

20 represents a bridle of cloth or other suitable flexible material which surrounds the mass of lilaments near the hub and is secured thereto by stitches 21, the bridle confining the backwardly bent series of filaments upon the inner series.

The mop thus constructed is adapted to be manufactured to good advantage by blind people and is relatively inexpensive, so that when the filaments are worn nearly to the hub, the mop may be removed from the handle and discarded, a new mop being substituted for it.

The ears 17 projecting from opposite sides of the hub constitute forming members-yorspreaders, whi'ehwimpartiamapproximately1 elliptical form to the inner end portion of the mop as indicated by Fig. 5, the mop havsides'.-
